Prevents being KOed from full HP, leaving 1 HP instead. Protects against the one-hit KO moves regardless of HP.
When this Pokémon is at full HP, any hit that would knock it out will instead leave it with 1 HP. Regardless of its current HP, it is also immune to the one-hit KO moves: Fissure, Guillotine, Horn Drill, and Sheer Cold. If this Pokémon is holding a Focus Sash, this ability takes precedence and the item will not be consumed.
